TYPE-WRITING- MACHINE.

7 To all whom it may concern:

This inventlon relates to typewriting machines, and is especiallyadapted to be used in a front-strike typewriting machine, to enablework-sheets to be collated or adjusted relatively to'one another at theposition most convenient tothe typist, namely, the front of the machine.

The invention is herein disclosed as applied to an Underwood typewritingmachine. The platen is thrown up clear of the feed rolls, so that awork-sheet horizontally inserted may pass straight beneath the platen.The platen is thrown up rearwardly, thus providing ample space in whichthe typist may inspect and handle the work-sheets. The platen maynormally tend to swing into its upper position, so that the typist maymake ready the machine for the insertion of work-sheets by the mererelease of a latch, which normally holds the platen down .to cooperatewith the feed rolls in holding the work-sheets.

There may be provided one or more gages in the form of impaling .pinsmounted on the front of the typewriter carriage, to cooperate withperforations in the work-sheets. The gage or pin may be located where itwill not interfere with the manipulation of work-sheets in the ordinarymanner in a typewriting machine.

The sheets one by one are laid face down upon a table or rest at thefront of the carriage, with their rear portions extending under theplaten. The sheets are collated in various relationships by means of thecollating pins which rise from said table, to engage holes punched inthe side margins of the sheets. Usually one .pin at each side of thetable will be suflicient. After the sheets are collated, and while theyremain engaged by the pins, the platen is swung :down to printingposition, carrying down with it the rear portions of the sheets, untilthe latter are gripped between the platen and the usual bottom feedrolls. The sheets are thus always under control, and .may now bereleased from the plus.

Specification of Letters Patent.

The usual Other features and advantages will hereinafter appear.

In the accompanying drawings,

seen in Fig. 3, in which latter position a,

work-sheet 17 is adapted to be passed horizontally beneath the platen.

When the platen 4 is swung up to the Fig. 3 position, one or morework-sheets 17 may be adjusted on a vertical pin 18, which is mounted ona work-adjusting table in the form of a plate 19 fast to the frame ofthe carriage, said pin being placed well inwardly from the frame so asto bring the pin as close to the printing line as may be withoutbringing the pin into a position where it will be awkward to adjust awork-sheet thereon. Y a

As shown in Fig. 3, the work-sheet 17, when impaled on the pin 18, willextend nearly horizontally rearwardly so that the farther end 20thereof, which is the lower end of the work-sheet, may .reach toward andeven beyond the usual paper table 21, rest- 'mounted on said side plate10. *VVhen thus ing on the rear end thereof, as shown in .Fig, 3, Toenable work-sheets to beaccurately adjusted, there may be provided amargin gage, which may take the form of a second pin 22 alined with thepin 18.

After the work-sheet 17has been adjusted to the desired printing line,the platen 4 is swung downwardly by drawing on a handle 23 formed as anextension of the side plate 10, and the platen-may be caught in "thislower position by a spring-actuated catch 24, which is adapted to catchover a pin 25 drawn down, the platen 4 holds the works sheet against theusual feed rolls. 15 and 16. During the operation of drawing down theplaten'from its Fig. 3 positionfthe typist' may holdthework-sheet inposition by placing a thumb or finger upon the plate 19. To .20

do this most conveniently, the handle23'is placed at the right-hand sideof the machine to be manipulated by the right'.' hand, and

- the thumb or finger of the left hand may hold the work-sheet. I

After the platen has gripped. the work sheet against the feed rolls, thetyp-ist may remove the finger or thumb from the plate 19, thuspermitting the work-sheet to assume an upright position where it may bedetained by abar '26. This bar is mounted near the platen and made,fast'in' the plate;

' 19 and supported at its right-hand end in an extension 27 of the plate19, the bar 26 being sopositioned that it-is above the usual type guide28 into which'the type-bars 29 (Flg; 4) strike,, and also above the wingasc ales 30, with the result that. the bar 26,

tending to bend them.

protects. both the wing scales and the ribbon vibrator (not shown),which is adja cent the type guide 28, in such away that even if thework-sheet is stiff, 'it will "not in- ]urethe'wing scales or ribbonvibrator by I 'In order that the bar may obstruct the new of thework-sheet as little as possible after be ng written upon, the bar 26 ismadeas small as is consistent with the necessary strength, and may be inthe form of a heavy wire having reduced ends '31, which are engaged bythe turned-up ends 32 'of the plate 19 and of the extension 27.

The pin-18 is advantageously placed well within the carriage on ahorizontal portion swings up and down in its. swing frame,

against overthrow when released from the swing frame.

'wardly under the pressure 0 'with the pins 18 and 22, and these pins33,-

34' may serve either as impaling'pins or as margin gages. For removingor adjusting work-sheets, the feed rolls 15. and 16 may be provided withthe usual casting-off mechanism 35.

To rotate the platen, there may be provided the usual knobs 36, which,in .the present invention, are usually 'mounted on stub shafts 37, andto enable both the knobs 36 and the line-space lever 5 to always havethe platen under control, the platen may be 1 'constantly gearedtheretoby mechanism somewhat analogous to the mechanism of the I usual fan-foldtypewriting machines. :For this purpose, a stub shaft 37, which is conjnected both to a knob 36 and to the line- 1 space mechanism, is providedwith a gear wheel 38 constantly in mesh with an idle pinion 39 journaledon the stub shaft 14, .8 and the platen shaft 7 is'provided with a gearWheel 41, which is also constantly in mesh with the idle pinion 39. Theconnections, therefore, are such that .as the platen 9 the side platesthereof always hold the pinions 38, 39 and 41 in mesh with each other,thus keeping the platen always under the control of the rotatingmechanism.

At the opposite end f l he carriage a similar idle pinion 42 may meshwith a gear Wheel 43 fast to the platen shaft 8 and with a gear wheel 44fast to the usual other knoh-(notshown), thus preserving the symmetry ofconstruction which conduces to the.

accuracy of the machine.

To facilitate-the operative in rapldly adjusting and -removingwork-sheets, the

platen swing frame is adapted to be swung up verticallyandjautomatically by means 'of spring 45, which bears against the sldepla 10, and may be coiled around the stub shaft 13. andanchored againsta. pin 46 in the platen shift frame.

In order toprevent the platen from be-,

ing thrown too far over, the side plate 10 may be extended rearwardly at47, forming an extension which strikes against the pin 46 to "limit thethrow of the swing frame. The catch 24 may be operated by a fingerpiece48, which is conveniently located I at the right-hand of the machine,and 006perates with a stop 48 to hold the catch By having the pin orpins 18, 22, 33 and 34 mounted on the typewriter carriage it ispossi-bleto locate'work-sheetson the platen, whatever the position of thetypewriter carriage may, be along the usual scale plate 49. This makesit possible to utilize the bent portion 50 of the plate 19 as a rest forthe finger and as a curve to guide thework-sheet when it is bein bentdown the platen,

thus avoiding any tendency to form a sharp bend or ridge over the bar26, with the reing pins at both sides of, the machine it becomespossible to collate work-sheets extending only part way across as isshown in said Fig.5, the sheet 51 extending only part way from the left,and the sheet 52 extending only part way from the right. It is possiblefor the typist to hold both these sheets against slipping whiletheplaten is swinging down by resting the fingers of one or both hands 'onthe upper part of the plate 19.

In order to enable the work-sheets to be rapidly and accurately adjustedwithout the need of the typist turning them over to inspect them, thelines on which writing is to be done below the usual cross rulings 54,maybe numbered as shown at 55,and

the perforations may j be correspondingly numbered on the back of thesheet, as shown at 56. It will be noted thatthe numberings 55 do notcoincide with the numberings 56.

.The numberings on the back of the sheet are so placed that when a givennumbering is at the pin l8, the corresponding numbering 55 on the frontof the sheet will be atthe printing point when the platen is swung toits home position where the type 29- will write on the'face thereof. Theworksheet s'hownin Fig. 4 is als shown provided with the usual, rulings57, but the typist needpay no visual attention I to the adjustmentof-said rulings with ref- 'erence to the scales on the wing scales ofthe I typewriten'if the machine is properly adjusted, and theperforations 58 of the worksheet are properly adjusted with referencethereto, since such proper adjustment brings f-it about that theimpaling of a sheet on the pin 18 will bring the rulings onthe faceof-the sheet in proper relations to thescal'es and escapement' mechanismof the type- I writer, a

The usual knob 59 on which the pointer 60 is mounted is preferably cutdown to a i to. coijper-ate wlth a work-sheet adjusted on said pin, toenable the operative to adjust the I level with the top of the plate19,- thus permitting a work-sheet to lie smoothly on said table.

Variations may be resorted to within the scope of the invention, andportions'of the improvements may be used without others.
